I just had my first "check up" since purchase...one issue I was finding was a slight whistling, but what seems like excessive air coming through/passing by the side door.(Jayco Melbourne) the dealership said they thought it was the extra holes in the front bar of the awning(I didn't think so). Then when I tried to take the tech out to check things, the instant I got him off the lot, they were phoning him to come back in, thus we didn't get much further, and only at maybe 45 mph.
Since then, I have encountered again this problem...which is only really heard as soon as the vehicle gets up to at least 55(+) mph. I still think that there's not enough "stuff" around the door ...
Has anyone else encountered this, and how did you solve it?
